Returning to the stage with a vengeance, “Yippee Ki-Yay Merry Christmas: a Die Hard Musical Parody” is about grizzled NYPD cop Bruce McClane, and his quest to win back his estranged wife, Holly Generic, at her Christmas Eve office party at the Nakatomi Plaza in sunny LA, 1987. German terrorist Hans Olo and his henchmen take the cast and audience hostage, and it is up to Bruce – with some help from the LAPD, FBI and Arnold Schwartzen-Schnitzel – to save everyone before time runs out. Book and score conceived by Michael Shepherd Jordan, Alex Garday and Stephanie McCullough, with choreography from Sheena Laird and directed by Tiffani Moore Swalley.
